The last time Tottenham Hotspur and Millwall player each other, it was a 2001 pre-season friendly. Despite the meaningless nature of the game, it was marred by crowd trouble during which 30 police officers and three police horses were injured.

This Sunday, March 12, the two teams will face off in a game that actually matters: The quarter-final of the FA Cup, Britain's most prestigious cup football competition. Police, the clubs, and the Football Association (FA) are taking no risks.

When the draw for the quarter-final stage of the FA Cup was made last month, many took to fan forums and social media to bookmark the Spurs and Millwall clash as a potential risk for hooliganism.

The match was moved to a 2 p.m. kick-off time on a Sunday in order to reduce pre-match drinking, while Tottenham initially only provided Millwall with a match-day ticket allocation of 2,800 — a significant reduction on the maximum 15% (4,750) allowance it could have granted.

Hat-trick hero Harry Kane helped Tottenham to a 3-0 win over Fulham in the Round of 16.

After dialogue with a local Safety Advisory Group (consisting of police, ambulance services, the council, and the FA), Spurs granted Millwall a maximum 3,681 tickets.

This allocation has since been sold out and Millwall published a note on its official website urging those without tickets to watch the match on TV.

Business Insider contacted the Metropolitan Police to ask whether Sunday's match carried a hooliganism risk. It said it was aware of the game, but declined to reveal how much resource it is making available.

A spokesman said: "We police many games throughout the season and there are ratings for some matches. After this game, if there are incidents, we will look into them."

One football police official, Preston North End's officer Paul Elliott, has acknowledged that the game could present problems. In a knowing tweet after the draw, he said:

A Tottenham Hotspur spokesman told Business Insider: "We have a dialogue with the Metropolitan Police prior to every match we play and a robust management plan is in place."

Millwall booked their place in the FA Cup quarter-final after victory against Leicester City in the last 16. Leicester, though, filed a complaint to the FA over the "abuse, provocation and intimidation" its fans suffered in the loss.
